It's more his sort of bravery (7)
I believe the answer is:
heroism
'bravery' is the definition.
(heroism is brave behaviour)
'it's more his sort' is the wordplay.
'sort' is an anagram indicator.
'more'+'his'='morehis'
'morehis' anagrammed gives 'HEROISM'.
'of' is the link.
(Other definitions for heroism that I've seen before include "brave action" , "Outstanding courage" , "Very brave conduct or act of valour" , "Gallantry" , "Oh miser! (anag.)" .)
